文摘Based on the analyses of the lining technologies of the hot press formed carbon brick iu U.S.A., of the ce-ramic cup in France and of the creative self-baking car-bon brick in China,the technology of semi-graphitized car-bon block-ceramic brickwork has been studied and developed ,and has successfully ben used in No.7 blast furnace (2580m^3) at Anshan Irom and Steel Company and in No.3 blast furnace (1200m^3) at Taiyuan Iron and Steel Company,This paper puts fourward a feasible scheme for realization of long service lives of the bootms and the hearths of large-sized blast furaces in China.
文摘The different specimens of the Self-Baking Carbon Block are obtained by charging the baking temperature and time.The graphitizing degree G of the specimen is determined by the quantitiative X-ray diffraction.The relationships between G and temperature are expressed.The results show that the graphitizing process from amorphous carbon to graphite is apparent quasi-one-order and should be conducted above a critical temperature.1200K The transition rate increases with tenperature.
